I find it kinda hard to believe the account isn't hers, it lines up with her intelligence connections to be fucking around like this and the account posted about her interests
people claim the account posted in private subreddits but I don't find that very credible or even necessarily disqualifying, the lack of public activity is important either way
not publicly but there were claims that they did in modmail.
